Plot of variable importance measure from Random Forest.Betty, J. KreakieYing, FanTimothy, H. Keitt
Random forests are becoming increasingly popular in many scientific fields because they can cope with "small n large p" problems, complex interactions and even highly correlated predictor variables. Their variable importance measures have recently been s

This study aimed to investigate environmental variable importance in the association with under-five mortality using a random forest approach. Variable importance was explored in each sub-dataset of mortality cause: all-, natural-, and external-cause mortality. The nature of this study differed from...
Random forest model and variable importance’s As described previously, we derived a RF model to predict the BMI in this sample. Multiple imputation was included in the calculation of the standardized importance scoresTjfor each predictor variablexjin the dataset. A total of 100 imputations were ...
Here, if we treat permutation importance applied to the underlying relationship as the quantity to be estimated, and our application of permutation impor- tance to an estimated random forest as an estimate, we can observe considerable bias due to measuring the random forest at extrapolation. The ...

I am working with the r-package randomForest and have successfully made a random forest model and an importance plot. I am working with a dichotomous response and several categorical predictors. However, I can't figure out how to make partial dependence plots for my categorical variables. I ha...
6.4.4.4 Step3: Selection of Best Subset of Features Using Random Forest After the selection of the 50 features, RF was performed to select the best subset features for modeling. RF is a classification method, but it also provides feature importance (Breiman, 2001). The RF algorithm estimates ...
